DNA can encode man-made genetic programs that perform specific tasks in live cells. The delivery of a DNA program to a cell is akin to sending a message. Lapique and Benenson show that a DNA message can be compressed like a computer file to reduce its size, and can then be decompressed in a cell after being delivered. The cover is an artist's depiction of the decompression process that requires a site-specific recombinase protein and takes place in the nucleus. The fact that the chemical structure of DNA is also an information carrier is illustrated using the wireframe extrapolation.
The demonstration of room-temperature ferromagnetism in an atomically thin layer broadens the prospects for device applications of 2D van der Waals materials.
Religious people tend to have a different view of nanotechnology than non-religious people. Chris Toumey explores whether there are also different views between different religious groups.
Reducing the dimensionality of paramagnetic VSe2 results in the emergence of ferromagnetism that is observed in a monolayer and up to room temperature.
Intercalation of copper and cobalt atoms into n-type SnS2 enables seamless integration of metal, and n- and p-type semiconductors in one parent 2D material.
When a helix-based liquid crystal that incorporates molecular motors is illuminated locally with intensity above a certain threshold, a continuous, regular and unidirectional rotation emerges.
Left-handed amyloid fibrils form nematic and right-handed cholesteric tactoids with confinement-induced transitions from an ordered to an ordered state.
Nanoporous carbon composite membranes exhibit 100% salt rejection and high water flux due to the interfacial sieving effect and the fast transport of vapour in carbon pores, respectively.
